Clue 5

Division facts (1-12) — the last clue

Dividing the recovered emeralds equally among the guard posts unlocks the final file.

First solve each problem. Then find each answer in the list below and cross that sentence out. One sentence will be left — that's exactly what the villain did!

Step 1 — solve these

60 ÷ 12 = ?

77 ÷ 7 = ?

30 ÷ 3 = ?
